French
La cheville ouvrière
Meaning: The linchpin — the person or thing on which an entire operation turns.
Literally: The working pin
Example: “La secrétaire de l'association en est la véritable cheville ouvrière.” — The association's secretary is the real linchpin of the whole thing.
Origin: The cheville ouvrière is the kingpin bolt joining a cart's forecarriage to its body, carrying the load and allowing the vehicle to steer. Remove it and the whole thing comes apart, which is precisely the claim being made about the person.
